Drive-Size Conversion
This three-piece set converts a 3/8-inch female drive to a 1/4-inch male drive, letting mechanics and DIYers use smaller sockets on larger ratchets. Each adapter is forged from chrome-molybdenum steel with a black phosphate coating that resists corrosion during automotive and household repairs.
Pin-Retention Ready
A cross-drilled hole in every adapter accepts a locking pin and O-ring, so sockets stay secured under impact loads. The 28 mm overall length keeps the profile short enough for tight engine bays while still providing the reach needed for recessed fasteners.
Impact-Rated Durability
The Cr-Mo alloy absorbs repeated hammer blows without rounding or cracking, maintaining drive integrity over long sessions. Phosphated surfaces shed rust and reduce galling, so the adapters stay reliable through sustained, high-torque use.

Questions about this item
Will the 28 mm length limit access to deep fasteners in tight engine bays?
The 28 mm overall length keeps the profile short so the adapter fits into recessed bolt holes where a longer extension would bottom out.
Does the black phosphate finish hold up to daily impact-gun heat without galling?
The phosphated Chrome-Moly steel surface resists corrosion and reduces friction, so repeated high-torque cycles do not cause the adapter to seize or gall.
Do I need a pin-and-O-ring kit to lock sockets onto the 3/8-inch female drive?
Each adapter has a drilled pin hole, so you must supply your own retaining pin and O-ring to secure impact sockets during use.
